LOS ANGELES — Jayson Tatum produced a dazzling 31-point display as the Boston Celtics dominated the Dallas Mavericks 106-88 to clinch a record-breaking 18th NBA championship crown on Monday (Tuesday in Manila).
Humbled by Dallas in a 38-point game four drubbing on Friday, Boston slammed the door on any chance of a Mavericks fightback to seal a 4-1 series victory at an electric TD Garden.
Tatum spearheaded a superb performance at both ends of the floor as Boston pulled clear of their arch-rival Los Angeles Lakers to stand alone with 18 NBA titles.
The emphatic win came 16 years to the day after Boston's last NBA Finals win -- over the Lakers -- in 2008.
'Oh my God. It's a surreal feeling. We did it,' a jubilant Tatum exclaimed after the triumph. 'We did it -- oh my God, we did it!'
'First of all, God is the greatest, not 'cause we won, but to put me in positions to maximize my God-given ability to surround me with these guys and with my family.
'This is an incredible feeling. I'm lost for words. I'm sorry.'
Jaylen Brown, who was named Finals Most valuable Player, gave Tatum scoring support with 21 points, while Jrue Holiday added 15 and Derrick White 14.
The defeat marked a miserable end to the finals for Dallas duo Luka Doncic and Kyrie Irving, who had led the Western Conference fifth seeds on an improbable giant-killing journey to the NBA Finals.
Doncic, sensational during the Mavs' game four rout of the Celtics, finished with 28 points.
But Irving scored a meagre 15 points while being taunted with chants of 'Kyrie sucks!' by Celtics fans still rankled by his departure from the team in 2019.
Top-seeded Boston meanwhile reasserted their superiority in convincing fashion after their game four blowout, leading by double digits from late in the second quarter until the final buzzer.
The Celtics laid the foundations for victory with a controlled first-half performance that saw them open up a 67-46 lead at the break.
Payton Pritchard put the seal on a superb first two quarters for Boston, launching a mammoth buzzer-beating three-pointer from near half-way that gave the Celtics a 21-point advantage.
Boston had been swiftly into their groove early on, building a 9-2 advantage in the first quarter with their swarming defense never allowing Dallas to build any kind of rhythm.
No respite for Mavs
